The second edition of this book appears two years after the first. I deliberately left the body of the book unchanged other than add a new introduction. if only to underscore the point: there were plenty of warnings! The significance of the timing of the first edition book is obvious to anyone who has lived through our strange times: September 2020. That was six months following the lockdown of most of the world during which places where people might “congregate” were shut by governments. The reason was to avoid, mitigate, eliminate maybe, or otherwise diminish the disease impact of the virus that caused Covid. This was before the vaccine came out, before the Great Barrington Declaration, and before data on excess deaths the world over showed vast carnage from these policy decisions. The second edition appears two years later. The topic put me to work trying to understand the thinking, a process which took me back through the history of pandemics, the relationship between infectious disease and freedom, and the origin of lockdown ideology in 2005. The times during which it was written were beyond strange. People went full medieval in every way in which that term can be understood. There was public flogging in the form of masking and the abolition of fun, feudalistic segregation and disease shaming, the practical end of most medical care unless it was for Covid, the scapegoating of non-compliers, and a turn to other pre-modern forms. All of this became worse once the non-sterilizing vaccines appeared on the market that many if not most people were forced to accept or lose their jobs. Writing now September 2022, I cannot even imagine going through the pain of putting this research together again. I’m very pleased it was done then because now this book survives as a marker that there was dissent, if nothing else. This was a period of time – still is today – when vast numbers of people feel betrayed by technology, media, politicians, and even their one-time intellectual heroes. It is a time of grave destruction with still-broken supply chains, roaring inflation, mass cultural demoralization, labor market confusions, and terrible uncertainty about the future. Let us hope, too, that it is a period of rebuilding, however quietly it is taking place. Starting the Brownstone Institute is part of that for me. So many others have joined. Today we published articles from all over the world since so many around the world have shared in this suffering. ~ Jeffrey Tucker, September 2022

AN INSTANT #1 NEW YORK TIMES BESTSELLER The bestselling author of The Parasitic Mind shows why empathy in politics leads to civilizational collapse. What happens when a society elevates victimhood to a virtue and decides that punishment is cruel? You get the disease Dr. Gad Saad calls suicidal empathy. And the West may be terminally infected. In his new book, Suicidal Empathy, Saad unleashes a blistering critique of maladaptively irrational altruism that has gripped our culture. This mind parasite hijacked the empathy module of our progressive elite, leading to a catastrophic miscalibration of moral priorities. The results are everywhere: from coddling violent criminals to protecting rapists to branding self-defense as toxic behavior. We are witnessing a civilization in rapid decline. Lunatic policies are instituted because we prioritize the feelings of ostensibly marginalized groups over The Truth, criminals over victims, and squatters over homeowners. This is not humane; it’s an active dismantling of the pillars that keep us safe and free. This crisis of empathy creates a horrifying system of inverse morality where the strong and successful are demonized, and the destructive are celebrated. Just look at the insane inversions we tolerate daily: we prefer illegal migrants over our own legal citizens and veterans, permit drug addicts to threaten children’s safety in parks, and elevate transgender 'women' above biological women in sports and safe spaces. Common sense is dying in a deluge of misguided compassion. Suicidal Empathy is your wake-up call. Stop ignoring your survival instincts in the name of political correctness. This isn't just misguided policy; it is the ultimate expression of a culture actively choosing its own demise.

The classic history of the political and economic devastation wrought by runaway inflation in Weimar Germany—“brilliant” (Guardian)   In 1923, with its currency effectively worthless (the exchange rate in December of that year was one dollar to 4,200,000,000,000 marks), the German republic was all but reduced to a barter economy. Expensive cigars, artworks, and jewels were routinely exchanged for staples such as bread; a cinema ticket could be bought for a lump of coal; and a bottle of paraffin for a silk shirt. People watched helplessly as their life savings disappeared and their loved ones starved. Germany's finances descended into chaos, with severe social unrest in its wake.   Money may no longer be physically printed and distributed in the voluminous quantities of 1923. However, "quantitative easing," that modern euphemism for surreptitious deficit financing in an electronic era, can no less become an assault on monetary discipline. Whatever the reason for a country's deficit— necessity or profligacy, unwillingness to tax or blindness to expenditure—it is beguiling to suppose that if the day of reckoning is postponed economic recovery will come in time to prevent higher unemployment or deeper recession. What if it does not? Germany in 1923 provides a vivid, compelling, sobering moral tale.

The new book from one of TIME's 2021 most influential people Author was in Forbes 30 Under 30 Hall of Fame "A crucial contribution to development of a new technology that will impact all of our lives.” –Laura Shin, host of the Unchained podcast and author of The Cryptopians: Idealism, Greed, Lies, and the Making of the First Big Cryptocurrency Craze “Vitalik Buterin is one of the most influential creators of our generation....Like most of his work, it is sure to become a must-read.”–Camila Russo, author of The Infinite Machine, founder of The Defiant The ideas behind Ethereum in the words of its founder, describing a radical vision for more than a digital currency—reinventing organizations, economics, and democracy itself in the age of the internet. When he was only nineteen years old, in late 2013, Vitalik Buterin published a visionary paper outlining the ideas behind what would become Ethereum. He proposed to take what Bitcoin did for currency—replace government and corporate power with power shared among users—and apply it to everyday apps, organizations, and society as a whole. Now, less than a decade later, Ethereum is the second-most-valuable cryptocurrency and serves as the foundation for the weird new world of NFT artworks, virtual real estate in the metaverse, and decentralized autonomous organizations. The essays in Proof of Stake have guided Ethereum’s community of radicals and builders. Here for the first time they are collected from across the internet for new readers. They reveal Buterin as a lively, creative thinker, relentlessly curious and adventuresome in exploring the consequences of his invention. His writing stands in contrast to the hype that so often accompanies crypto in the public imagination. He presents it instead as a fascinating set of social, economic, and political possibilities, opening a window into a conversation that far more of us could be having. Media scholar Nathan Schneiderprovides introductions and notes.

Have you, like the rest of the world, speculated as to the identity of Satoshi Nakamoto, anonymous creator of Bitcoin? The world's first cryptocurrency, Bitcoin went online in 2009 and has since revolutionized our concepts of currency and money. Not supported by any government or central bank, completely electronic, Bitcoin is a virtual currency based on advanced cryptographic systems. Like the currency he created, the identity of Bitcoin's creator Satoshi Nakamoto is virtual, existing only online. The Nakamoto persona, which may represent an individual or a group, exists only in the online publications that introduced and explained Bitcoin during its earliest days. Here, collected and professionally published for the first time are the essential writings that detail Bitcoin's creation. Included are • Satoshi Nakamoto Emails and Posts on Computer Forums Presented in Chronological Order • Bitcoin Fundamentals Presented in Layman's Terms • Bitcoin's Potential and Profound Economic Implications • The Seminal Paper Which Started It All The Book of Satoshi provides a convenient way to parse through what Bitcoin's creator wrote over the span of the two years that constituted his "public life" before he disappeared from the Internet . . . at least under the name Satoshi Nakamoto. Beginning on November 1st 2009 with the publication of the seminal paper describing Bitcoin, this public life ends at about the time PC World speculated as to a possible link between Bitcoin and WikiLeaks, the infamous website that publishes leaked classified materials. Was there a connection? You be the judge. Nakamoto's true identity may never be known. Therefore the writings reproduced here are probably all the world will ever hear from him concerning Bitcoin's creation, workings, and theoretical basis. Want to learn more about Bitcoin? Go directly to the source-the writings of the creator himself, Satoshi Nakamoto!
